I downloaded a driver for a camcorder (Sony USB Driver) so that it could connect to my computer (Windows Vista - 32 bit). The driver was incompatible with Vista, so to install it I used the process decribed here

(ran it in compatibility mode for XP).

I now suspect that this driver is causing issues in my PC. However, when I go to the "Uninstall or Change a Program" screen and try to select and uninstall it, I get the error message that "USB driver cannot be installed in the current version of Windows"

I tried using device manager to uninstall it too, but I couldn't find the driver there.
I also tried to run the setup file again so that it would give me the option to uninstall it, but that just prompted me to install it again.

Is there any other way for me to uninstall this driver, or to run the uninstaller in compatibility mode for XP?
